The CyanogenMod team has certainly been busy this week; a few days ago we saw the first CyanogenMod 9 nightly builds appear for the AT&T Galaxy S II and HP Touchpad, and now the original Samsung Galaxy S can join in the party, too.

Definition: A "nightly" is a bleeding edge release that is built on a daily basis, usually at night after a full day's worth of new code has been committed.

It could oftentimes be unstable and not properly tested, lacking any changelogs, but eventually evolving into alphas, betas, release candidates, and finally stable releases.

Nightlies are available for both the i9000 and the i9000B, which is the Brazilian variant of the device, from the CyanogenMod downloads site.
